REG103FA-2.5 TI LDO Regulator | TO-263 (DDPAK-5) | 2.5V Fixed Output, 500mA

Product Overview

The REG103FA-2.5 from Texas Instruments is a high-performance, low-dropout (LDO) voltage regulator designed to deliver a fixed 2.5V output with a maximum current of 500mA. Housed in a TO-263 (DDPAK-5) package, this device offers excellent line and load regulation, making it ideal for noise-sensitive applications. Its low dropout voltage (typically 115mV at 500mA) ensures efficient operation even when the input voltage is close to the output. The REG103FA-2.5 features a low quiescent current of 500µA and a shutdown mode that reduces current to 0.5µA, extending battery life in portable devices. With built-in overcurrent and thermal protection, it provides reliable performance in demanding environments.
